Creating Language Plugin not used for new language

[Roland Plüss]

I'm trying to get the DUChain stuff working. I'm using the python plugin
as example. I've done now the following:
- parsed the test-source into an AST (Flex + KDevelop-PG-QT)
- created DUContext for namespaces/classes/interface to get a first
working example
- assigned the DUContext in ParseJob::run() using setDuChain()
- called highlightDUChain() after setDuChain()
- notified KDevelop using DUChain::self()->emitUpdateReady(document(),
duChain());

Nevertheless I'm seeing no syntax highlighting in the document nor does
the code browser show any namespaces, classes nor interfaces I've created.

I used the DumpChain from PythonPlugin to verify the chain I set up so
far is correct (well, except for the column output in the debug code is
off... the real values are correct):

What could I be missing? Is there something special I need to do in a
language plugin to make DUChain I've created for a document to be used
by KDevelop? I've no idea where to look since I think I've done it
similar to how the python plugin is doing it.
